The KFDG4V32C20NZVMU1H720 valve belongs to the Proportional Valves series from Vickers and is used to regulate hydraulic flow and pressure in automated circuits. It is solenoid-controlled, so electrical signals drive spool movement, and its 24 V DC coil matches common machine control supplies. A spring-centered design returns the spool to neutral when power is removed, maintaining system safety. The unit handles a rated port flow of 20 L/min, giving predictable throughput for medium-duty actuators, while a maximum pressure limit of 350 bar defines the safe operating envelope. Meter-in/meter-out metering permits balanced control during extension and retraction strokes. Installation is simplified by an ISO 4401-03 / NFPA D03 / CETOP 3 / NG06 mounting interface that mates with standard subplates. Planning envelope depth is set by a product length of 270.002 mm.
An ISO 4400 electrical connector with fitted plugs provides quick plug-in wiring and consistent environmental sealing. A built-in feedback sensor tracks spool position for closed-loop accuracy, and required fluid cleanliness of 17/15/12 micron minimizes wear on precision edges. The valve accepts AW oils or non-alkyl phosphate esters, allowing use with common mineral or fire-resistant fluids. The design includes no manual override, eliminating unintended manual actuation, and there are no on-board electronics, so users must supply an external amplifier for proportional control. Cabinet layout is aided by a product width of 48.006 mm and a height of 87.122 mm, dimensions that keep the assembly compact inside manifold blocks.
